Trigger Finger
Quality care provided by an Orthopaedic surgeon
Trigger finger, also known as stenosing tenosynovitis, is a condition where a finger or thumb becomes stuck in a bent position and may "click" or "snap" when straightened. This occurs when the tendon in the finger becomes irritated and inflamed, making it difficult to glide smoothly through the surrounding sheath.
Dr Oscar Brumby-Rendell of Adelaide offers his hand and upper limb surgeon expertise for both non-surgical and surgical treatments for trigger finger to relieve pain, restore smooth motion, and improve hand function.
Causes of Trigger Finger
Trigger finger is caused by inflammation of the tendon sheath in the finger or thumb. This leads to narrowing of the space through which the tendon moves, causing the finger to catch or lock.
Trigger finger may be developed due to the following:
- Overuse - Hobbies and occupations that require frequent and repeated hand movements or gripping for lengthy periods
- Age - Individuals between 40 and 60 years of age are at a greater risk of trigger finger development.
- Gender - Trigger finger is more common in women.
- Health conditions - Including rheumatoid arthritis and diabetes
- Carpal tunnel surgery - Trigger finger is often associated with carpal tunnel syndrome and flexor tenosynovitis.
Symptoms of Trigger Finger
Trigger finger symptoms typically develop gradually and may include:
-
Pain or tenderness at the base of the affected finger or thumb
-
Clicking, snapping, or locking sensation when bending or straightening the finger
-
Stiffness, especially in the morning
-
A small lump (nodule) at the base of the finger
-
In severe cases, the finger may become locked in a bent position
Early treatment often results in better outcomes and may prevent permanent stiffness or joint contractures.
Diagnosis of Trigger Finger
Diagnosis of trigger finger is usually made through a clinical examination. Dr Brumby-Rendell will assess your hand function, finger movement, and presence of tenderness or locking. In most cases, no imaging is required.
Treatments
Non-Surgical Treatments
In mild to moderate cases, non-surgical management may be effective in relieving symptoms. These include:
-
Activity modification to reduce aggravating movements
-
Splinting the affected finger, especially at night
-
Anti-inflammatory medications (NSAIDs)
-
Corticosteroid injection, which can reduce inflammation and allow smoother tendon movement
Many patients experience significant relief after one or two injections, especially in early-stage trigger finger.
Surgical Treatments
Surgery may be recommended if:
-
Symptoms persist despite conservative treatment
-
The finger is stuck in a locked or bent position
-
There is significant pain or loss of hand function
Dr Brumby-Rendell performs a minimally invasive trigger finger release procedure, which involves releasing the tight portion of the tendon sheath to allow the tendon to glide freely. The procedure is typically done under local anaesthesia as a day case.
